I'm running XP and an 8800GT.

I get the total freeze/crash when I get to the soft push training. Once I get too close to the ladies and start going through the crowd, it just slows down to a crawl and I have to manually restart.

Looks to me like the similar result here is the 8800gt. I've tried all the beta/nvidia drivers and to no avail.

I run Crysis beautifully on highest settings (I even use the DX10 hack for XP) 1400x900 on an AMD Socket 939 (oh yeah!) X2 4400+, 2 GB ram, etc and never have problems with any other games. This could be nvidia/ubi's coding errors. I hope to see a patch soon.

why do you say oh yeah after saying its a socket 939? that is prety much the basic socket for the dual cores the high end dual cores actualy us the AM2 socket that supports DDR2 ram.

but the game slowing down in a crowd could be down to increased demand on the graphics card other people have complained of fram skipping and the likes making the game unplayable if you look at these you will find a fix that may help you.

I've just received my copy of Assassins Creed in the mail yesterday and eagerly installed and started it up only to find it crash from exactly the same issue most people are also suffering in this forum.

Symptoms:

*Game runs exquisitely for around 3-15mins depending on Nvidia control panel settings and game settings.

*I Notice when I run around alot, then stop for a few seconds (i.e jump in a bail of hay or something) and if i start moving again it crashes the whole system upon first movement.

*Red and/or Green artifacts cover the foreground of the screen, whilst in the background the game world starts producing abnormal triangular polygonal artifacts at random.

*10-20secs from crash point the whole system stops responding and forced reset is inevitable.


I have experienced this exact type of crash in other games before (namely ARMA - Armed Assault with it's infamous Geforce 8800 issues) BUT only on very rare occasions and not to the extent Assassins Creed is crashing.

I hope this gives our patching buddies a good enough picture of what us supportive consumers are suffering from so a patch can be made promptly.

Because I'm sure i'm speaking for everyone in this forum, we really want to play this game.

Is this bug vista only or does it happen under xp as well?
(Just installed xp to test this, but it will take me still a bit)

PS: I made a ~10 hours memtest and ~7hours 3dmark loop (1680*1050, all maxed, only graphics tests), so I am fairly sure that getting this artifacts doesnt relate to faulty memory sticks and the video card running to hot.

After a clean install of XP I can say: Its the same - It crashes as well with nice graphic artifacts...
Artifacts look like this:

Hello friends,

First of all I hope no one takes wrongly to my remarks but the EVGA 8800GTs overclock MUCH better than other brands. Its a proven record with all their 8800 series cards. Their fans run powerfully although they need a 3rd party program like rivatuner or coolbits to manually control the fan speed. I own one and I run AC non stop without problems. Mine is an SSC edition which is a factory overclocked version. XFX is second best but still lacks a bit.

I suggest not overclocking if u don't have decent cooling OR overclocking using a benchmarking software until you get hit with anomalies. Its all trial and error. So good luck folks.

regards,

Jay

There is a discussion in the nvidia forums regarding these crashes as well (without solution so far):
http://forums.nvidia.com/index.php?s=a69b851fb4bfdd23e5...11dc&showtopic=64432
Apparently a very common bug. (And @: starjay001, people with EVGA 8800 GT SSC edition are affected as well)

Ok, I think this is not an Nvidia problem. I've run Unreal Tournament III, Crysis, Call of Duty 4, Bioshock, Company of Heroes, World in Conflict, and other games at max effects and 1024 x 768 resolution on my system for hours without a fault. I even manage to play through Assassin's Creed for hours until I get to the final approach to Robert in Part 6 of the game. Then as soon as I get 10 or more guys fighting me, my system locks up.

Specs as follows:
BFG nforce 680i motherboard
Intel Core 2 quad Q6600 processor
2 gigs of Corsair dominator DDR2 8600 RAM
BFG geforce 8800 GTX watercooled w/768 DDR3 RAM
Windows Vista Ultimate

Just verified I have the latest drivers for video card and motherboard from nvidia. I haven't overclocked any part of my system, the CPU and GPU are water cooled, and the CPU surface runs at 91F which is normal when I'm playing games and pushing the video card. I'm going to try to reload the video drivers to see if that helps, but I've not had this problem with any of my other games.

Just an interesting update to report here. I got to the end of Memory Bank 2, and was completely unable to finish a dialogue in the lab with the female lab assistant. It would lock up every time before completing (I tried variations in video settings about 9-10 times to attempt to get through it). The lockup was the same as previous errors, in which display driver "nvlddmkm.sys" had stopped responding. A similar issue was reported elsewhere here:

Getting the "NV4_Disp" error message? *Please Read*

I was able to get past the lockups during that scene by following the advice posted in a thread here on unplugging the network card:

Freezes during in-game events, page 2

It appeared to be an issue with some sort of DRM software checking in with an IP address registered to Ubisoft in Ontario. The first post by "whybuybeta" in that thread gives some specifics after he watched outbound traffic on his system.

That may not be the only issue, as that poster also reported watching video memory usage with rivatuner and being able to predict just before it's going to crash because the video memory was approaching the upper limit of the card. Apparently the game may have memory management/culling issues, according to that poster's observations.

So... we may have a couple of issues here. I can report that unplugging the network card did make performance better in a particular repeatable problem at the end of Memory Bank 2. I re-enabled the NIC (network card) after that, and found that it did crash about 25 minutes into Memory Bank 3. Going to try playing without network connectivity and see how far I get before the next crash.

Hope that is helpful to folks.

Ive been getting the crash after playing with the blue artifacts. This is something ive only ever had in one other game which is Test Drive Unlimited, but the artifacts are red in that. I believe thats to do with one being Directx9 the other 10. Both are games from next gen consoles.

I just managed to play for an hour with no crashes. Which i have never done before.

I play the game in 1920x1200 everything full.

What i did was, download nTune from the Nvidia website. Installed it, then in the nVidia control panel set the fan to manual and put it up to 100%.

The fan was on auto at 30%. The noise was much much much louder, but i went and played the game and yeah it worked for an hour, no crash. Earlier it was working for 10-15 mins.

Just set the fan back to auto when i was done to keep the noise down.
I shall test this more, but right off the bat this worked.

It also actually made me notice something, playing call of duty 4, the fan would get louder after playing for a while. This was never the case with AC or TDU. I'm wondering if there's something stopping the automatic fan adjustment with these console to PC games.... Its just a guess based on little evidence... but yeah..

hopefully this keeps working and can help others out

I updated my video drivers to 169.25 and for grins unplug my network cable and I played for a few hours straight yesterday. Those seem to be working for me.

I wanted to take a bit to help others with whatever crashing issues they might be having with this game by reporting what I've found out about my system after some extensive tweaking and finally being able to run the game for a fair bit without crashing:

1) There has been advice given about the game giving calls to the Internet in various threads, and here, and I can confirm that blocking the game from such things (removing Windows Firewall exceptions is sufficient) does improve stability drastically.

2) As others have said, this game runs much worse than other high end, demanding games that have come before it. Even though the game does push a system, it does so far more than the graphics would suggest it should. There is more than likely more than a little bit of erroneous coding in the game that might one day be fixed via a patch or patches, but in the meantime, this is what helped extend my playtime:

a) Keep your system cool! I only use air cooling, although admittedly I have one of the better cases in terms of overall airflow and moving hot air out of the case. Still, keeping the temperatures down will really help. The extra strain this game creates is going to heat up both the GPU and the CPU more than normal, so as others have said, crank up the GPU's fan a bit using RivaTuner or nTune, whichever you prefer. Realistically, you should be doing this anyway if you're doing high end gaming, as cooling off the GPU is going to enhance your overall gaming experience across the board.

b) If you overclock right up to the bleeding edge, you might need to back it off a bit. I normally run my system at 3.6GHz on my Q6600, but this game really takes its toll on all my resources, so I found backing it off to 3.2GHz helped a lot. I don't notice much of a difference in how my system performs, either, and the stability is worth it.

I have had pretty much every crash that others have reported, including GPU, memory, and system crashes, all based on a combination of heat and resource hogging (due to what I believe is a memory leak) and I can say that now that my system is running very cool under load (CPU stays below 50C under load), the crashes are typically the minor ones that only crash the game, not the system, so it makes it much easier to get back in and start playing again, and my overall play time is right around 1-3 hours.

Hi. This is my problem:
Very often the shuts down without reason. After so of these "Shut Downs" I can't restart the Game again and I have to restart my Computer.
Also sometimes the game freezes my whole computer so that I have to restart it.
My pc is :

Microsoft Windows XP Media Center Edition (Service Pack 2);
HP Pavilion Intel (R);
Pentium D CPU 2,8GHz;
1,00 GB Ram;
Ati Radeon 1600 (512 mb);
Directx 9.0 (last version of March)

By the way, the game runs well with max settings, but the problem still the same with max or lower settings.
Please some1 help!!!

I got this artefacts-problem that many have, and the only thing we can do is waiting for a patch to fix this I guess.

In response to sortakinda:

I just tested ac with my gpu fans at 80% (so everything nice and cool) and with the firewall blocking the internet access of ac.
I just loaded the last savegame and went away, so I did not even move Altair. 5 minutes later the blue artifacts came and the well known nvlddmkm.sys BSOD.

Unplayable...

So lets wait for a patch...

Edit:
Steam people are haveing the crashes as well.
Just found a second screenshot of how it looks:

Hello all,

I had the same crashes, but i found the solution for the Asus 8800GT, there is a bios update voor the 8800GT i flashed the card an the problem is GONE!!!!

Well, first off, your system is not awfully robust, meaning it's going to have a hard time handling the resource load that this game produces, so keep as much background stuff from happening as possible and focus on just running the game. Also, you didn't mention if you'd blocked the game from accessing the Internet or not. If you haven't done this, then that alone could solve your problems. The only other suggestion is to keep the system cool by making sure the insides are as open as possible and blowing out the dust with compressed air.

I blocked the game from accessing the Internet and I started the game just before I the desktop apears on the screen... and this still happen
Do you think that buy a memmory card could solve this problem?

Ohh wow good thing I dind't change my video card like I was about to. I thought it was corrupted video memory and that she was done for.

Ok here's the info I have and how I seem to have stopped the problem for now.

I use a Geforce 8800GT BFG OC2 512mo.
I played AC for a couple of hours with no problem at first.

Then I got my Artic cooling accelero heatsink in the mail and proceeded to replace my card's onboard fan with it to do better cooling and less noise. (This card sounds like a vacuum cleaner in your PC).

After installing the heatsink I start to play Assassin's Creed: 9 minutes later I get the red artefacts and I'm like OMG I toasted my new video card. I tried playing World of Warcraft: no problem at all. I try playing Call of Duty 4. after 15 min I get the red artefacts crashing the PC again. I play 15 min of Guitar Hero PC and the same red artefacts appear and crash my PC. My verdict: Some of my video memory is toasted and only high texture games seem to do it. However I am thinking that I now have to buy a new video card, because from past experience bad video memory = Nothing to do about that.

But then in the meantime my Turbo fan that goes with the artic cooling accelero arrives in the mail with a new 120mm backside fan. (I had ordered those before the problems.)

I decide to put them on to see if it would change anything.

The result so far is that Assassin's Creed now plays very well and that the GPU never exceeds 54 degrees. I have been playing for the past 2 hours with no problems at all. (apart from the silly exit game method, but that's another story).

Sorry for the long text, but all this to say that for some reason the heat seem to have this effect.

The only thing that I am still wondering is how come it affected other games too. Games that had never done this problem before. Could it be that this is driver related and that something stays in the memory ?

IMm no expert. I just hope that these information can help in pinpointing the problem.

Hi again.
The update for the asus is for all 8800 series from asus, read to be sure!!It fixed the crahses for me!!!!

Good luck to you all.
